Re: 18mm vs 23mm af speed?

I suppose I should shoot both for the same shot. But I've noticed a hesitancy in the 23 acquiring focus and some hunting at times in low light. I've never noticed anything with the 18 other than it simply locks focus fairly quickly. The 18 is used far more often than the 23 (focal and size, not AF). Of my lenses, the only one I'd consider fast is the 16.
